Review: BMW 3 Series (2019)

More spacious than before. Upgraded engines. Very refined. 330e PHEV with low 33g/km CO2 initially comes in under £40,000. With 36 mile range, qualifies for 10% BIK from April 2020.

Saloons not as practical as SUVs in many people's eyes. Options on 330e soon push the price into £465pa VED bracket.

BMW 3 Series (2019): At A Glance

The G20 BMW 3-Series is wider, longer and lighter than its predecessor - with BMW insisting that it will remain at the top of its class in terms of handling. Still clearly a 3-Series, the latest model features a larger kidney grille and headlights similar to the bigger 5 Series. 

A longer wheelbase translates to a roomier cabin. BMW is promising an extra 11mm of rear legroom and more headroom for those in the front and back. Larger doors should make getting in and out of the new 3 Series easier, while the rear seats can accommodate three child seats. With the rear seats left up, boot space is 480 litres, while the rear seats can be dropped 40:20:40 to increase luggage capacity.

There's more kit as standard, with the entry-level model featuring an 8.8-inch central touchscreen infotainment system, increasing to a 10.3-inch system on the M Sport model. Apple CarPlay is standard across the range, although drivers will have to pay for a subscription service after the first year.

Like the Mercedes-Benz 'Hey Mercedes' personal assistant that made its passenger car debut in the A-Class, drivers and passengers in the new 3 Series will be able to access functions and retrieve information by saying 'Hey BMW'.

Described as 'the ideal co-driver', the personal assistant will learn your routines and habits allowing it to answer questions and even provide casual conversation ('Hey BMW, what is the meaning of life?' is an example provided by BMW).

The G20 3-Series comes with a digital key as per bigger models in the range, allowing it to be locked and unlocked from a smartphone.

From launch, buyers can choose from a range of four-cylinder engines in the 320d diesel and 330i petrol. The diesel produces 190PS with peak torque of 400Nm, taking it to 62mph in 7.1 seconds (automatic: 6.8 seconds), while the four-wheel-drive xDrive version takes 6.9 seconds.

Advertised fuel consumption is 64.2mpg (automatic: 67.3mpg) for the 320d and 62.8mpg for the 320d xDrive. The 320d’s CO2 emissions are 115g/km (automatic: 110g/km) while the 320d xDrive’s CO2 emissions are 118g/km. 

The 330i has 258PS, matches the diesel's 400Nm torque figure, hits 62mph in 5.8 seconds and has a top speed limited to 155mph. Combined fuel consumption is 48.7mpg while CO2 emissions are 132g/km.

A plug-in hybrid version badged the 330e arrived in late 2019, with 292PS combined, 33g/km CO2 and up to a 36 mile EV range. Mid-range fuel economy 50.4mpg.

1.5 litre three-cylinder petrol that shares its engine with the MINI Hatch from 2020.

The G20 BMW 3-Series went on sale on 9 March 2019 with prices starting at £33,610 for the BMW 320d and topping out at £37,660 for the BMW 330i.

What's the BMW 3 Series (2019) like to drive?

The G20 BMW 330e is as good to drive as expected, but marred by the optional 225/40 R19 and 255/35 R19 rear tyres fitted to the test car that give a hard ride. (Should be better on standard 225/45 fronts and 255/40 rears.)

Definitely feels bigger than the F30 3-Series. Has a new digital cockpit offering Android Auto and Apple Car Play. i-Drive seems more intuitive than before (but maybe just from getting used to it). 

Has 4th generation lithium-ion battery and 'Anticipatory Hybrid Drive' providing intelligent distribution of electric energy and eDrive in urban areas with a range of between 31 - 50 miles.

If left in Sport mode the charge in the hybrid battery is conserved so its range can be used in urban environments.

I want to buy an EV or PHEV but I worry about changing from manual to auto - what do you think?

When electric vehicles are discussed, one thing I do not see mentioned is whether older drivers should change from manual to electric. Electric vehicles must be automatic or equivalent to an automatic. My journeys are totally suitable for an electric vehicle or Plug-In Hybrid; 90% short trips. With home charging, the new BMW 330e with its 40-mile range on electric would be ideal (if somewhat extravagant). I would rarely have to visit a garage but I do want a vehicle that would do 250 miles before needing a charge. However, I passed my driving test in 1962 and my other half tells me not to touch automatics. My daughter’s car was hit by a car driven by an elderly driver that accidentally went 30-foot across a car park from a parking space and my neighbour, driving an automatic, wrote off five cars in a car park in a similar fashion. I am quite happy on the outside lane of the motorway in my Porsche Boxster (manual) and I don’t think going to an electric vehicle would be a problem after a couple of hundred miles of practice but I am a bit wary of making the change. What are your views on this?
I'm a big fan of automatics - they're easier and more relaxing to drive and make a lot of sense unless you particularly enjoy changing gears. A plug-in hybrid sounds like it'd suit your needs very well, assuming you can charge it at home. But there are more affordable PHEVs on the market than the 330e - consider a Volkswagen Passat PHEV or Hyundai Ioniq PHEV.
